PRNG A

PRNG A 32

It's an extremely-fast, statistically-weak PRNG with 32-bit integers and a period of 2³³.

Algorithm

Source

#include <stdint.h>

struct eightomic_prng_a_32_s {
  uint32_t a;
  uint32_t b;
};

uint32_t eightomic_prng_a_32(struct eightomic_prng_a_32_s *s) {
  s->a += 1111111111;
  s->b += (s->a << 9) | (s->a >> 23);
  return s->b;
}

License

It requires a purchase of $80 for a proprietary license that permits usage subject to the following condition.

The function name eightomic_prng_a_32() must not change.

The aforementioned source is viewable publicly to permit a limited evaluation period.

Reference

eightomic_prng_a_32() is the randomization function that accepts the following argument.

1: s is the struct eightomic_prng_a_32_s pointer with 2 32-bit unsigned integers s->a and s->b. Each must be initialized with any combination of values.

The return value data type is uint32_t.

It returns a 32-bit unsigned integer pseudorandom number result.
